Itunes sells sound loops that do not work seamlessly on iPod

You sell applications meant to be looped seamlessly on ITunes, identified as no fade, but they do not work on ipods, either MD480LL, Version 1.0.4 PC, SN C7RJNGTDF0GT, nor on Model MA97BLL, Version 1.1.3 PC, SN 7W7459K8Y0P.

This one in particular runs for 1 minute and 12 seconds, and has a noticeable hiccup when it repeats.

The tracks do work correctly on iPhone 6 Plus, and on the computer that hosts iTunes. A useful application for an unused iPod is for a sound generator, but specific use of gapless noise as sold is not usable, and not noted on your site that it is not usable on iPods.

Please update iTunes to display this information prominently for future buyers who are upset over spending any amount of money for something that does not work.

Or sell versions that ae longer than 1-2 minutes, perhaps a gap every hour might not be as objectionable.

Please update your iTunes information!!!
